To all eff/7mm ymay 'concer/: i: y

' Be it known that l, Fiuinniuc C. Monroy, a citizen of the United StatesH residing in ew Haven, in thecountj.v of Xew Haven and State of Connecticut, have invented an lin,- provement in Tire-Building Machines, of which the following description, in connection with the accompanying drawings, isa

f It() specification, like let-ters on the drawings representing like parts. l

lThe .present invention relates to tire building machine, and is embodied in an iin- 'proved arrangement for smoothing down,-

and shaping the successive layers of fabric on a-rotatable shaping core after the fabric I has been stretched and laid upon the periphveral surface of said core.

` Une purpose of the invention is to arrange the apparatus so that-the complex movement 'of the'shaping device which is employed, as

` said device moves over and lshapes the fabric on the core7 will be fully automatic and synchronous with therotary movement of the j core, so that .thespinnin'g .in operation isenrelates to this feature' of the invention, it is tirol)7 independent of the judgment of the operative, and'absolutel;7 uniform through out. lthe process of building up the carcass.`

A further feature of the invention relates lto novelnieans for producing the necessari movement of the smoothing and shaping de- Vices with relation to the core, and, as far as immaterial whether the operation is fully automatic or not.-

1 n accordance with the invention'l thek smoothing and shaping device, which will. be

hereinafter termed a spinning roll, is mounted on a support which is autoniaticalliY movable' in a directionsubstantially parallel to i. 'im

the axis of the core so that. the periphery of the spinning roll follows and remains in conl tact with the curved. surface of the core; While the spinning roll itself is movable on 'fthe said support in a direction parallel to its own axis, so that the peripheral part or edge of l the roll gradually changes its position with rela-tion tothe surface of the fabric durfing the-,rotation of the core.

`Itis desirable, though not essential. that two rolls should be employed. so that the.

laver of fabric at both sides of the longitudi- 'nail median line thereof can be smoothed down and pressed into conformityY with the core at a single operation; andnfor purposes of illustration, the apparatus is shown as provided with two rolls which act simultaneously. There is, however, no essential co* operation between the. rolls, and either roll can be used independently. In the construction shown to illustrate the invention, the rolls are mounted on movable supports having guideways on ay supplewith relation tothe core. y

Figure l is aplan view of an apparatus embodying theinvention; and Fig". 2 is a similar View of the same showing the parts in the position reached at, or approximately at, the end of the wiping-in operation.

Referring to Fig. l., the rotating core l is shown as mounted on a shaft adapted to be driven in any suitable or usual way, :is-.bhv a belt on a pulley 3; and thc said core is shown as having'laid thereon one layer of fabric 4.-. The rolls arecarried on a swinging frame 5 which is shown as pivotalljv' connected at- 6 with a part of the main fraineof the machine, and adapted to-be locked in the operative position shown by means ot' a lock ingr pin 7. The rolls themselves are lindicated as thin disks 8 having rounded edges adapted to engage thel outer surfaceof the fabric L and each roll is rotatable uponan axle 9 along which the hub .of the roll longitudinally movable. These axles l) areconA nected with supports l which are capable of movement toward the axis of the core l. the,said supports being mounted on guides l2 forming part of a supplemental frame 13 which is adjustable on the swinging frame for the purpose. of adapting the device for use with cores of different sizes. In the construction shown, the main part. of the supple-mental frame 13 is provided with slots il engaged by nuts l5 secured on bolts ll whichv are stationary with relation to the swinging frame 5. so that the said frame 13 can be noved toward or from the core l and locked in the position desired. i llach'support adapted to lm vieldiigly drawn along its guide. springs 17 being herein shown as constituting themcans for bringing about this result. The supports are further shown as provided with handles 18 whereby the action of the springs can ybe manuali)7 supplemented, if necessary. q The supports are further shown as provided with a suitable lockingV desice for holding tlm ,Separated when the apparatus is not in use, the supplemental frame. 13 benieiital frame which is movable or adjustable ingshown as provided with a'pivot-ed lever thatwhen the lever is turned into line with the guides .12, the two supports willbe heldat their 'point of widest separation. lOne of the 'links 21 isv shown as provided with a lost motion connection'v with one ofv leavet-lie lrolls 8 free to come into equal l1-9 having an actuating handle 20, the said- 'fle'ver being connected-by means of' links 2l with the two supports 10, thefa'ivis of the "lever being between and in linewith the points' of connection-with the supports, so

thev supports, as indicated at 22,s as to l.Contact with lthe fabric on the core 1 under the action of the springs 17.-

As shown in Fig. 1,'the frame 5 is swung y into positio'n for operation, and the locking lever 19 has-been moved from itsflocking position, so 'that the two rolls 8 rare firmlyl pressed into engagement with the fabric through the action 'of the springs 17... In order to produce the lengthwise' movement' of the rolls 8 towa-rd 'the axis of the core l when fthe core begins to rotate, the rotary movement lof the rolls, which is causedby' peripheral contact :with the fabric-on the core is utilized to move the saidv rolls with relation to the supports 10. As herein shown, eachl of the rolls 8 is provided with a gear 23, shown as forming a part of the hub? of the roll, said gearl meshing with ajgear 24, which is secured on a screw threaded stem 25. This screw threaded stenicoperates with a female thread formed ina n ut 26A which extendslaterally into va cylindrical' guide" 27 forming part of the support 10,

this guide fitting and surrounding thescrew threaded stem It is obvious that the en.

tire guide might be screw threaded, if desired: the purpose, however, of using thenut 26 being to provide means for readily restoring the parts to their normal 'condition after the operation has bcenfinished,.the nut 26 .beingf shown as mounted on astem 28 roll 8 willturn the screw threaded stein 25, so that the said stem, the gear carried there 'b v, aiid the roll cooperating with said gear,

will be moved with. relation to the `frame from the position shown iii Figi. toward the positionshown inlfig. "2, and during this movement, the supports 10 will be moved lz'itera-lly toward the core 1 and toward eachother; if both .sides are operated upoii jat'onc'e. *so that the rolls will be held closely in contact withuthe fabric through- The final 'positionof-'the fout, spinning inthe fabric', lat the' same-.time

having a tendency -to push the same toward' .the axis of the core,l so .t iat an efectual shaping or stretching. actio isQbt-ainedllls can'be positively .deteimined yby mea stops .32 which 'are shownbolts threaded the said'stopssbeing adapted'V to comeinto engagement with the sides of the supplemental 'frame 13 after the supports'fhave been moved to the `limit desired.

In Fig.r 2 the nuti26'is shown-as with?, drawn from engagement with thethreaded stem 25, although, in actual Ioperatioivi,"this nut will not usually be withdrawniuntilthe locking lever. 19 has been moved-to locking position, and theparts. are ready to 'be re'- stored to their normal position.y An adjustable'stopelis also shown as located. on the face of the support 10 to' engage the'gea'r 24 and limit the-return movement of the wiper rolls and; determine the normal position thereof.

-Vhile the actual movement-of; the rolls in 'completing the shaping of the fabric, is, ,in-

Iall cases, a resultant of aniovei'nent along ,7.0 i of adjustablef.

the axis of therolls'and a movement genen l ally transverse thereto,l the generaljdirection I of the movement depends upon which part of the fabric the rolls engage first; and the vactual directioiiof travel of the rolls along their axes is immaterial, sop-far as relates to the invention, solongas such ,direct-ion of 4.travel is a proximately tangential' to the curvature o the` core throughout its shaping portion.

, What I; claim-isz ioo In a Vtire building machine, -a rotatable#-v core .adapted to receive fa. strip of fabric',

combined with a roll yieldingly heldin contact .with the fabric on the core.; lmeans for rotating-.the core;" and means whereby the rotation of the coreis caused toproduce `a movement of the'said .roll in ai direction toward the la-Xis Aof the core.
